The invention concerns an air-cleaning plant of the through-flow type with a central element comprising one or several sheets of synthetic rubber-type foam plastic, also first and second air-permeable outer elements in sheet form of interwoven fibres of synthetic organic material capable of holding a negative electrostatic charge. This plant stands out in that it comprises first and second series of rods made of a thermoplastic capable of holding a positive electrostatic charge, whereby the series of rods compress the central element and make contact with the exterior of the central element, also the exterior of the sheet elements are arranged outside the respective series of rods. <IMAGE> |
